3 Claims.

My Invention relates to screed supporting means.

An important object of my invention is to provide a means for properlypositioning the screeds upon which the flnished flooring is laid.

A further object of my invention is to provide a means for positioningthe screeds that will be easily accessible from above.

A still further object of my invention is to provide a screedpositioning device that is simple in construction, eilicient inoperation, and extremely inexpensive to manufacture.

Other objects and advantages of my invention will be apparent during thecourse of the following description.

In the accompanying drawing, forming a part of this speciflcation, andin which like numerals are employed to designate like parts throughoutthe same,

Figure 1 is a side elevation, showing parts in section, of a deviceembodying my invention,

Figure 2 is a front elevation of the same,

Figure 3 ls a bottom plan view of my device, and

. Figure 4 is a side elevation of the same.

In the drawing, wherein for the purpose of illustration is shown apreferred embodiment of my invention, the numeral 5 designates asubstantially circular plate having diametrically opposed flanges 6extending therefrom, adapted to be bent upwardly and fastened to thewooden screed 1 by means of nails 8 or the like. Openings 5 are providedin the plate 5 to permit a suitable tool attached to a carpenters braceor the like to be inserted therein and the plate 5 rotated to arequisite level. Depending centrally from the plate is a screw-threadedshank 9 which is secured to the plate by means of a rivet lo or thelike. The lower part of the shank 9 is screw threaded and is providedwith a nut II screw threadedly engaged thereon.

The operation of my device is as follows:

In the construction of both concrete and wooden buildings, it iscustomary to provide a subiioor of concrete over which the flnishingfloor is laid. The finishing floor is carried by and nailed to screedssupported above the concrete underfloor. The rough floor, however, isnot leveled with any degree of accuracy when laid and it thereforebecomes necessary to accurately level the screeds upon which thefinishing floor is laid. This is most frequently done by wedgng blocksbeneath the screed or by filling in beneath the same with plaster orconcrete so that the upper faces thereof are at the requisite level.This is a difiicult and arduous task and is rareiy accompiished with anygreat degree of success.

In my invention, I coat the screw-threaded shank 9 with a heavy coatingl2 of caulking eompound. grease, pitch or any substance which willpermit the concrete to harden therearound and not adhere to the outersurface thereof. The nut ll is left clean of any coating in order topermit the concrete to harden therearound and securely hold the sameagainst displaoement. o The screed holding devices are embedded in theconcrete at intervals sufiicient to properly hold the screeds that areto be supported thereby. The screeds 1 are placed on the circular plate5 and the letter rotated until the screeds are po- 15 sitioned at therequisite level. The rotating of the shank 9 is easily aflected due tothe protective coating .I2 therearound. When the screeds have beenproperly leveled. the flanges 6, which are of a lesser thickness thanthe circular plate 20 5, may be bent upwardly along the sides of thescreeds i and firmly secured thereto. When this has been accomplished,the flnished flooring I3 is then laid in an accurate and eflicientmanner.

It is to be understood that the form of my in- .25 vention herewithshown and described is to be taken asa preferred example of the same andvarious changes in the size, shape and arrangement of parts may beresorted to without departing from the spirit of my Invention or thescope of 30 the appended claims.

Having thus described my invention. I claim:

1. In a building construction, a composite concrete floor, a nutimmovably embedded a substantia1 distance beneath the surface of thecon- 35 crete, a screed supporting member having flanges adapted toengage the sides of the said screed, and a screw-threaded shankdepending from the screed supporting member and screw-threadedlyengaging said nut, said shank being coated With 4o a substance toprevent the bonding of the concrete therewith and to permit the shank tobe freely rotatable after the concrete has set.

2. A screed posltioner comprising a nut firmly embedded in the concretebase floor of a build- 45 ing, a screed supportingmember having meansintegral therewith to secure the said screed thereon, and ascrew-threaded shank attached to said screed supporting member andscrew-threadedly engaged to said nut, said shank being coated with 50lubricant to prevent the bonding of the concrete therewith and to permitthe shank to be freely rotatable after the concrete has set.

3. In a building construction including a composite concrete floor, anut embedded a substah- 55 ahank dependinz from the base and e the nut.said slmnk being coated with a suitable lubricant to prevent the hondinzof the concrete therewith and to peflnlt the shank to be ireelyrotatable within the said nui; after the concrete has 5 set.
